BIS monitors provide information clinically relevant to the adjustment of dosages of sedating medications. Use of a BIS monitor may affect overall costs of sedation in critically ill patients. BIS monitors are ...

Editor’s key points † Automatic feedback control depends on having a reliable, measurable control variable. † An automatic system for closed-loop administration of i.v. anaesthesia drugs was compared with manual control. † Bispectral index and a compound analgesia score were used as the target controls. † Time within excellent (≤10%) and good (11–20%) range of the two targets was better with th...

OBJECTIVE The bispectral index (BIS) is a parameter derived by electroencephalography (EEG) which provides a direct measurement of the effects of sedatives and anesthetics on the brain and offers guidance on the adequacy of anesthesia. The literature lacks studies on BIS monitoring in pediatric patients with congenital brain disease undergoing general anesthesia. CLINICAL FEATURES A 13-year-o...

UNLABELLED Assessment of depth of anesthesia is the basis in anesthesiologists work because the occurrence of awareness during general anesthesia is important due to stress, which is caused in the patient at that moment, and due to complications that may arise later. There are subjective and objective methods used to estimate the depth of anesthesia. The aim of this study was to assess the dept...

We studied four electrophysiological variables (bispectral index (BIS), 95% spectral edge frequency (SEF), median frequency (MF) and auditory evoked potential index (AEP index) in 10 patients during emergence from anaesthesia. We compared correlation of the signals with gradually decreasing calculated blood propofol concentrations, and evaluated the signal differences between preinduction and e...

The bispectral index (BIS) is a processed neurophysiological electroencephalographic parameter that may be used to evaluate the depth of sedation in critically ill children. Triltsch and colleagues attempted to correlate BIS scores with a commonly used clinical sedation scoring system. They were able to demonstrate good correlation during deep sedation and in cases where the electrical impedanc...

BACKGROUND AND OBJECTIVES To the best of our knowledge, the value of the plasma effect site equilibration rate constant (k(e0)) of propofol has not been reported in Chinese patients. The aim of this prospective, randomized study was to examine the characteristics of the time to peak effect (T(PEAK)) of propofol, a pharmacokinetic-independent descriptor of blood-brain equilibration, and k(e0) de...

UNLABELLED Memory for intraoperative events may arise from inadequate anesthesia when the hypnotic state is not continuously monitored. Electroencephalogram bispectral index (BIS) enables monitoring of the hypnotic state and titration of anesthesia to an adequate level (BIS 40 to 60). At this level, preserved memory function has been observed in trauma patients. We investigated memory formation...
